Hi there! It's because the button should read "Hide List" when the block is displayed, not when it's hidden. When the block has a style of "none", it is hidden and then we want the button to say "Show List". It would be odd to have a "Hide List" button when there's no list visible, right? :smiley:

Hope this helps! :sparkles:
